You are definitely not the only one:
Technology-wise, I agree it would be better if this worked the same on all operating systems.
On the other hand, while I understand that 4k displays are all the rage, there's a point where it doesn't make sense to use such a high resolution for everything. Personally, for day to day use, I still often scale down the resolution to 1366x768 even when my screen can handle more than that. I do have pretty good eyeballs myself, it's just more comfortable and efficient this way; for me anyway.
